auto increment with MySQL

hi, when creating a table in design view in the embedded datbase, it is straightforward to get a primary key that auto-increments. You fill in the key name, select integer (integer), and a yes/no box appears in the lower part of the screen for auto-increment.

The same does not seem to happen when attempting the same in MySQL, whether connected to a localhost database or over the internet. In both cases I am connecting using JDBC with the Oracle recommended connector.

I can create an auto incrmement field by connecting to the mysql database using the mysql client.

I am not clear if I am doing something wrong, forgetting something, or whether this is a gap in the Oracle JDBC class.

Any advice =======

Edit 20th Aug: Additional detail

If I open a table created from the mysql cli that has an autofield, the <autofield> value shows on new records and this works normally and shows <autofield> in the relevant "cell", as your screenshot shows.

However, when I edit that table and select the row defining that field, the Autovalue drop down never appears.

If I copy & paste the table the copy loses the autovalue.

If Base offers to create a new PK for the copy table, the checkbox for AutoValue is greyed out.

My Base is version 5.2.7.2 and is using Oracle Java 1.8.0.181 so when I downloaded the connector it seemed sensible to use mysql-connector-java8.0.11.jar

When I instaled it, I did the "Test Class" and it seemed to load OK (but then I know it partly works...)

Do you recommend I change to the java.5.1 connector?

If so, should I also downgrade the Java runtime that was installed before I consciously did anything to choose a JRE?RE does your Base use?

And if so, how would I downgrade the runtime? I am worried that other things in my OS might depend on Java 8 if I do downgrade it...

ON the other side of the argument, there is something clunky going on here ... I can get Firebird, FlameRobin, and MySQL running ish, but none of them in a fully featured way.... the common factor seems to be appreciated?the JRE as the respctive connectors are different.

I did wonder if the difference was caused by using a local connection rather than the net, but I can't get AutoValue to work on a test/demo server running the latest MySQL version at db4free.net

In the meantime the work-around is to create those tables using the cli. For production work that is what I would do anyway; for prototyping I prefer to use a GUI to tweak things and test variations....

If I make any change to that field, it loses its AutoField attribute.

If I copy & paste the table the copy loses the autovalue.

If Base offers to create a new PK for the copy table, the checkbox for AutoValue is greyed out.out. Altogether it seems clear that Base is not communicationg this fact to the underlying database.
